Description

[Detailed description of the invention] The present invention relates to the installation of temperature controllers such as temperature fuses used in water heaters, and in particular provides a water heater that can be installed with a quick response to abnormal temperature rises. It is something to do.

Examples thereof will be described below based on the drawings.

Reference numeral 1 denotes a water heater main body, which includes a rectangular cylindrical outer cylinder 2 having a rectangular planar shape, a bottom cover 3 that closes the lower opening of the outer cylinder 2, and the bottom cover 3.
a bottom plate 4 that closes the bottom opening of the outer cylinder 2; 6, a band-shaped heater 8 wrapped around the outer bottom of the inner cylinder 6, and an opening edge of the upper surface of the outer cylinder 2 and the inner cylinder. The frame body 10 is configured to connect and fix the upper opening edge of the outer cylinder 2, and an outer lid 11 that is rotatably inserted into the frame body 10 and closes the upper opening of the outer cylinder 2 in a freely openable/closable manner. ing.

The outer bottom surface of the inner cylinder 6 is connected to a mounting portion 1 provided on the bottom cover 3.
2 by a connecting member 13.

14 is a socket attached to the side surface of the bottom cover 3;
A rounded square rod 15 connected to the heater 8 is arranged inside it.

Reference numeral 16 denotes a ridge-shaped holding metal fitting, which is spot-welded to the outer bottom surface of the inner cylinder 6 so as to be close to the heater 8, and has an opening facing the heater 8.

That is, the distal end 16a of the holding fitting 16 is directed toward the heater 8, and the entire holding fitting 16 has an elastic force.

Then, by utilizing the tension of the holding fitting 16, a temperature controller 20 such as a temperature fuse is held between the outer bottom surface of the inner cylinder 6 and the holding fitting 16, such as a temperature fuse, which stops the current supply when the heater 8 is abnormally heated. ing.

21 is a tube that protects the temperature controller 20.

Reference numeral 22 denotes a handle provided along the length direction of the cylindrical portion 2.

Note that the holding fitting 16 is not limited to the L-shape, but may have any shape as long as it has an opening facing the heater 8.

25 is a thermostat attached to the outer surface of the inner cylinder 6, and is set to keep the water at an appropriate temperature after it has boiled.

Reference numeral 26 denotes a spout which is integrally formed in the frame body 10 and communicates with the inside of the inner cylinder 6.

The spout 26 has a gutter shape as shown in the drawings,
The top and tip are open.

A locking rib 27 is formed on the outer periphery of the tip of the spout 26, and a stop rib 28 is formed on the outer periphery of the base.

Furthermore, a notch 29, 29 is formed at the top of the inner wall of the spout 26, and a protrusion 30 is formed at the bottom of the inner wall.

Reference numeral 31 denotes an opening/closing plate disposed within the spout 26, which has locking portions 32.32 integrally formed on both sides of the upper portion.
32 is inserted and locked into the notch 29, 29 to make the opening/closing plate 31 freely rotatable.

A cylindrical cap 35 is inserted to cover the spout 26.

At this time, the cap 35 is held in contact with the locking rib 27 and the stop rib 28.

When the cap 35 is inserted and engaged with the spout 26, the opening/closing plate 31 is also prevented from being removed.

Reference numeral 33 denotes a rectangular inner lid with a pin 34 installed on the upper surface of the inner cylinder 6, which forms a raised part 35 on the outer periphery, and a gasket 36 is attached to the raised part 35 to open the upper opening of the inner cylinder 6. Obstruction.

A steam hole 40 is bored at a suitable position in the inner lid 33.

On the other hand, a groove is formed on the outer periphery of the lower surface of the outer lid 11 to form a communication portion 4.
1 and a pin receiving portion 42 is formed at the center of the lower surface edge.

When the inner cover 33 is attached to the lower surface of the outer cover 11 and the outer cover 11 is engaged with the frame body 10 to close the upper opening of the outer cylinder 2, the inner cover 33 The upper opening of the inner cylinder 6 is closed, and the gasket 36 of the inner lid 33 is pressed against the lower surface of the outer lid 11, so that the inner lid 33 and the outer lid 11 form a sealed space A.

When the closed space A is formed, the communication portion 41 communicates the spout 26 with the closed space A.

According to such a configuration, the temperature controller 20 can be easily installed and removed by using the tension of the holding fitting 16, and since it is installed close to the heater 8, dry heating can be avoided. The abnormal heating of the heater 8 caused by
Since the opening of the heater 8 faces the beater 8, an abnormal temperature rise of only the heater 8 can be detected without being affected by the ambient temperature.

Since the present invention is constructed as described above, it is extremely easy to attach and detach the temperature controller, and the responsiveness of detecting abnormal heating of the heater of the temperature controller is greatly improved.
